profiles. The location and profiles did not change.

Re: [darktable-user] input color profile

[Coding Dave]

Are you talking about profiles extracted from Nikon NX Software or what
kind of profiles?

Re: [darktable-user] Turning Filmic on an off in 2.6.1 sometimes darkens the image

[Kneops]

Thanks for all the replies.

I did not report it as a bug yet because I first wanted to check with 
others if they experience the same problem.

Good to hear there is already a fix so fast! :)

Re: [darktable-user] lua script "Enable Generate Image Txt" question

[Sheridan Price]

Yes, I am running windows 10.

Oh well. I can still manually create and enter info into a text file and
use the existing mouse over feature to see it. I know that works as it was
what triggered my interest in the lua script.

Thanks everyone for your replies.

Sheridan

My question then, is what has changed *today* ???

We have not changed 2.6.1 version. Did you installed something? Any
hint?

Thanks,

Did you upgrade from 2.6.0 to 2.6.1?

Ok, so probably this:

https://github.com/darktable-org/darktable/issues/2178

Which is being worked on.

Re: [darktable-user] How can I find all monochrome images?

[Mark]

Thanks to both of you. I like Lorenzo's approach, because it seems very 
pragmatic and I don't mind doing some shell scripting.


I watched Bruce's video (https://www.youtube.com/watch?v=OF23NWCTepw) 
and checked the previous email discussion on various ways to get a 
monochromatic image 
(https://www.mail-archive.com/darktable-dev@lists.darktable.org/msg03786.html). 
That made me think whether it's possible to come up with a complete list 
of modules that support monochrome output in one way or another. So, 
here is my list summarizing some ways that have been mentioned before, 
and even a few more, sorted from "seems obvious" to "pretty obscure". :-)


- monochrome: on
- contrast brightness saturation: saturation -1
- color correction: saturation -1
- color zones: all nodes in saturation tab curve set to zero
- channel mixer: various settings
- color balance: input saturation 0% or output saturation 0%
- filmic: saturation 0%
- color look up table: preset
- low light vision: all nodes in curve set to zero, blue shift 0%
- soften: size 0%, saturation 0%, mix 100%
- colorize: saturation 0, source mix 100%
- vignetting: saturation -1, scale 0%, fall-off strength 0%

Of course, but maybe it is good enough for Mark. There are many ways to 
get a monochrome image but I suspect most user just go for the simplest one.


And he can extend this to the other modules he may have used to convert 
the image, manually removing tags from the false positives if necessary. 
Or just cover 90% of the images and do the rest manually.


Exactly. Personally, I mostly use the monochrome and color zones module, 
so I know what to look for in *my* image collection.


I do not see many alternatives anyway: you could inspect the exported 
images but it takes much more work (unless imagemagick can do the trick) 
and a few assumptions about the export folder for example.


Yes, thought about that, too. This "analytic" approach, looking directly 
at the final image, would probably be more robust (given a good enough 
definition of "monochrome image"). The drawback when you use an external 
tool like ImageMagick is that you need to have *all* processed images 
exported to disk. I usually only export subsets.


In my opinion the best solution would be implemented in darktable 
directly, analyzing the final image content by some criteria with 
configurable thresholds. Unfortunately, this also seems to be the 
solution with highest effort. So, I will try, what you, Lorenzo, 
suggested. Thanks again.

don't forget the "passthrough" mode in the demosaic module. ;)

[darktable-user] Re: output printer profiles [SOLVED]

[Daniel Wilhelm]

I think, darktable was upgraded from 2.6.0 to 2.6.1. But i found out,
that the notice "Output Color Profile missing, using sRGB" is NOT
related to the printer profile, but to the module "Output Profile". I
will check where is the notice coming from, because the output Profile
is set to sRGB, perhaps the standard sRGB profile is missing somewhere
in the tree...
But not related to the upgrade.. Sorry, and thank for the fast replies!

[darktable-user] Windows 10 and darktable-cmstest binary

[Sheridan Price]

Hello;

I notice that the above executable doesn't exist in the windows version of
darktable (I've installed 6.1). How then does one ensure that the color
management is setup properly?

Similarly the - cltest binary doesn't exist either.

Sheridan
